SPECIFICATION forming part of Letters Patent No. 574,41 1, dated January 5, 1897. Application filed June 2, 1896. Serial No, 593,986. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS BOYLE GAS- SETT, a citizen of the United States, residing at Taylor, in the county of WVilliamson and State of Texas, have invented a new and useful Windmill, of which the following is a specification.

The invention relates to improvements in windmills.

The object of the present invention is to improve the construction of windmills and to provide a simple, inexpensive, and efficient one adapted to dispense with the vane and to receive the wind from any direction and capable of being readily thrown out of and into operation when desired.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a portion of a windmill constructed in accordance with this invention, the blades being arranged in operative position. Fig. 2 is a similar View, the blades being thrown out of operation. Fig. 3 is an enlarged detail perspective view illustrating the manner of mounting the blades on the vertical shaft. Fig. 4; is a detail view of the shifting lever.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l and 2 designate blades extending outward from both sides of a vertical shaft 3 and forming a horizontal wind-wheel. The blades 1 and 2, which are disposed in pairs, are horizontally curved to enable them to receive and hold the wind, and the pairs of blades are arranged at right angles to each other, as illustrated in Fig. 1 of the accompanying drawings, when the windmill is in operation, and are adapted to be turned substantially parallel with each other, as illustrated in Fig. 2 of the accompanying drawings, when the windmill is out of operation.

The blades 1 and 2 are provided, respectively, with vertical bars 4 and 5 and sleeves G and 7. The sleeves 6 of the blades 1 are loosely mounted on the vertical shaft and capable of a'limited vertical and rotary movement, and the other sleeves 7 are keyed or otherwise fixed to the vertical shaft to connect the blades 2 rigid therewith. The sleeves 6 and 7 are alternately arranged, sufficient space being provided between them to permit the necessary vertical movement of the sleeves 6, and the latter have at their lower ends depending tapering projections 8, adapted to fit in corresponding recesses 9 of the upper ends of the sleeves 7 of the fixed blades 2, whereby the blades 1 are locked at right angles to the other blades to'maintain them in operative position.

The depending projections 8, which are held firmly in engagement with the notches or recesses 9 by the weight of the blades, are beveled at one side and are provided at the other side with a vertical shoulder, the recesses 9 being correspondingly shaped. When the blades are in operative position, the vertical shoulders of the projections and the recesses bear against each other and there is no liability of the blades being accidentally thrown out of operation through the force of the wind.

The bars 4: of the blades 1 are extended below the lower sleeves 7 of the blades 2 and are connected with a grooved pulley 10, which is swiveled to a shifting lever 11. The lever, which is arranged substantially horizontally when the windmill is 'in operation, is provided at its inner end with arms 12 for embracing the. grooved pulley 10, and an operating rope or wire 13 is attached to the outer end of the shifting lever to enable the inner end thereof to be thrown upward to lift the lower ends of the sleeves 6 out of engagement with the recesses or notches 9 of the sleeves 7. When the movable blades 1 are lifted out of engagement with the sleeves of the fixed blades 2, the wind operating on them will rotate them to a position substantially parallel with the blades 2, as illustrated in Fig. 2 of the accompanying drawings, and when the shifting lever is released the weight of the blades 1, together with the beveling of the adjacent ends of the sleeves, will carry them into operative position.

Any desired form of tower may be employed and any suitable form of gearing may be used for communicating motion from the vertical shaft to a pump or any other device or machine to be operated.

It will be seen that the windmill is exceedin gly simple and inexpensive in construction, that it is positive and reliable in operation, and that it dispenses with the vane and is adapted to receive the wind from any quarter.

It will also be apparent that the blades may be readily thrown out of operation and may be quickly returned to their operative position.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

\Vhat I claim is In a windmill, the combination of a horizontal \vin d-wheel com prising a vertical shaft, the movable and fixed blades each extending outward from both sides of said shaft and provided at their inner edges With vertical bars 4 and 5, the bars 4 being extended below the wind-wheel, the vertical sleeves 7 fixed to the shaft and provided at their upper ends with tapered'recesses and carrying the fixed blades, the bars 5 being secured to the sleeves 7, the movable sleeves 6 located above the sleeves 7 and provided with depending projeotions and connected with the bars 4 of the movable blades, said projections adapted to interlock with the said recesses to hold the fixed and movable blades at right angles to each other, a grooved pulley disposed horizontally and fixed to the extensions of the vertical bars at, and alever provided with arms and embracing the pulley and engaging the groove thereof, said lever being adapted to lift the movable sleeves out of engagement with the fixed sleeves, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed mysignature in the presence of two witnesses.
